Monstera Acuminata
''Monstera acuminata'', or shingle plant, is a species of flowering plant from family Araceae which is widespread from Mexico to Central America. It is abundant in central Petén and extends north to San Luis Potosí, making it the northernmost of the species of ''Monstera.'' Description ''Monstera acuminata'' germinates in the ground and grows horizontally as a low prostrate herb. The juvenile plant is much smaller and heart-shaped with thick, roundish, waxy leaves which grow in two ranks and overlap each other with the stem elliptic in cross section and internodes 1–5 cm long and asymmetric leaves. When it encounters a tree trunk, it uses its ageotropic anchoring roots to grow vertically. The adult plant appears similar to that of ''Monstera deliciosa'' and these leaves are developed when the plant reaches 15 feet and is an example of dimorphism. The leaves are smooth or papillose stem 2–3.5 cm thick with internodes 6–11 cm long. After it grows upwards, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Milpa
La Milpa is an archaeological site and an ancient Maya city within the Three River region of Northwest Belize bordering Mexico and Guatemala. La Milpa is located between the sites of Rio Azul and Lamanai. Currently, La Milpa lies within the nature preserve owned by the Programme for Belize, a non-profit organization. PfB acquired land for the preserve from the Coco-Cola Company, who purchased land in Belize in 1988 with the goals of tearing down the rainforest to create a citrus plantation, however donated the land to conservation and management project in 1990 and 1992. Following Caracol and Lamanai, La Milpa is the third largest site in Belize with the Main Plaza alone covering 18,000 square meters, making it one of the largest in the entire Maya region. Research History This site was first discovered in March 1938 by Sir J. Eric S. Thompson. Thompson’s work at La Milpa entailed mapping and excavating the Main Center, recording a total of 12 different stelae. Thompso ...

Karl Koch (botanist)
Karl Heinrich Emil Koch (6 June 1809 – 25 May 1879) was a German botanist. He is best known for his botanical explorations in the Caucasus region, including northeast Turkey. Most of his collections have today been lost. He is also known as the first professional horticultural officer in Germany. Biography He was born in Ettersburg near Weimar, Germany. He studied at the universities of Jena and Würzburg and taught, as privatdocent, at the University of Jena beginning 1834. He became an associate professor in 1836. He undertook a journey of research into southern Russia in 1836–38, and a second in 1843–44. The fruit of this second trip, in which he also visited Asia Minor, Great Armenia, the Caspian Sea, and the Caucasus Mountains,ADB:Koch, Karl In: |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Many species display very decorative leaves and flowers, and they are widely used for gardening; popular as indoor plants and also outdoor plants where climates are mild, and winter freezes will not generally occur. However, some temperate species are also very popular in Mediterranean-climate gardening, or in moderately cool temperate zones, such as ''Zantedeschia''. Description Species within Araceae are often rhizomatous or tuberous, and the leaves nearly always contain calcium oxa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petén Department
Petén is a department of Guatemala. It is geographically the northernmost department of Guatemala, as well as the largest by area at it accounts for about one third of Guatemala's area. The capital is Flores. The population at the mid-2018 official estimate was 595,548. Geography The Petén department is bordered on the east by Belize and by Mexico (with the Mexican states of Chiapas to the west, Tabasco to the northwest and Campeche to the north). To the south it borders the Guatemalan departments of Alta Verapaz and Izabal.ITMB Publishing Ltd. 2005. Much of the western border with Mexico is formed by the Usumacinta River and its tributary the Salinas River. Portions of the southern border of the department are formed by the rivers Gracias a Dios and Santa Isabel. The Petén lowlands are formed by a densely forested low-lying limestone plain featuring karstic topography. The area is crossed by low east-west oriented ridges of Cenozoic limestone and is characterised by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Luis Potosí
San Luis Potosí (), officially the Free and Sovereign State of San Luis Potosí ( es, Estado Libre y Soberano de San Luis Potosí), is one of the 32 states which compose the Federal Entities of Mexico. It is divided in 58 municipalities and its capital city is San Luis Potosí City. Located in Central Mexico, San Luis Potosí is bordered by seven other Mexican states: Nuevo León to the north; Tamaulipas to the north-east; Veracruz to the east; Hidalgo, Querétaro and Guanajuato to the south; and Zacatecas to north-west.

Monstera
''Monstera'' is a genus of 59 species of flowering plants in the arum family, Araceae, native to tropical regions of the Americas. Etymology The genus is named from the Latin word for "monstrous" or "abnormal", and refers to the unusual leaves with natural holes that members of the genus have. Description Growth pattern They are herbs or evergreen vines, growing to heights of in trees, climbing by means of aerial roots which act as hooks over branches; these roots will also grow into the soil to help support the plant. Since the plant roots both into the soil and over trees, it is considered a hemiepiphyte. Leaves The leaves are alternate, leathery, dark green, very large, from long (up to long in ''M. dubia'') and broad, often with holes in the leaf blade. The fenestrated leaves allow for the leaves to spread over greater area to increase sunlight exposure, and to allow light to reach other leaves below, by using less energy to produce and maintain the leaves. ...

Monstera Deliciosa
''Monstera deliciosa'', the Swiss cheese plant or split-leaf philodendron is a species of flowering plant native to tropical forests of southern Mexico, south to Panama. It has been introduced to many tropical areas, and has become a mildly invasive species in Hawaii, Seychelles, Ascension Island and the Society Islands. It is very widely grown in temperate zones as a houseplant. The common name "Swiss cheese plant" is also used for the related species from the same genus, ''Monstera adansonii''. The common name "split-leaf philodendron" is also used for the species '' Thaumatophyllum bipinnatifidum'', although neither species are in the genus ''Philodendron''. Names The specific epithet ''deliciosa'' means "delicious", referring to the edible fruit. The genus ''Monstera'' is named from the Latin word for "monstrous" or "abnormal", and refers to the unusual leaves with natural holes that members of the genus have. Its popular name as a houseplant of "Swiss cheese plant", or j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiepiphyte
A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary hemiepiphytes are root-climbers that begin as rooted vines growing upward from the forest floor, but later break their connection to the ground. When this happens, they may send down long roots to the ground.Mayo et al. "Araceae" in Kubitzki (1998b ''The families and genera of vascular plants''): "The root climbers and hemiepiphytes normally grow in humid forests, often very high in the canopy. When losing connection with the forest floor, they may send down long roots to the ground; such plants may be referred to as secondary hemiepiphytes. Hemiepiphytes and root climbers cling tightly to the bark of the host with negatively phototropic roots. Skototropism, an orientation movement towards a well-defined dark area, ha ...
